Paper Abstract

Optical response measurements are presented for granular, predominantly c-axis oriented crystalline YBaCuO films prepared by electron beam multi-layer evaporation to infrared radiation. The results appear to indicate that both bolometric and nonbolometric components contribute to the optical responses. For a typical patterned film of area 100 X 40 micrometers , the responsivity is above 103 v/w, the NEP is 10-11 w, and D* is 103 cm(Hz)1/2 /w to wavelength range of 8-14 micrometers , chopped at a frequency of 80 Hz.
